WERNER TESCHEMACHER, OF WERDEN-ON-THE-RUHR, GERMANY.

PACKING-RING.

1 '0 all whom it may concern:

Be it known that I, IVERNER Tnsonn- MACHER, a subject of the King of Prussia, and a resident of 2426 I-Iafenstrasse, en den-on-the-Ruhr, Germany, have invented a new and Improved Packing-Ring, of which the following is a full, clear, and exact description.

The invention relates to journal bearings for car axles and the like, and its object is to provide a new and improved arrangement for rendering the bearing dustproof and to insure uniform pressure on the split or open packing ring used for the purpose.

For the packing ring I employ a split or open ring made of felt or other suitable ma terial, and provided at its ends with apertured lugs, and extending through the latter is a guide rod carrying a coil spring attached at its middle to the rod and at its ends to the said lugs. By the action of this spring the ends of the ring, which overlap each other, are strained in opposite directions, and the entire ring is pressed with its inner surface against the axle, to form a dust proof packing.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the packing ring; Fig. 2 is a side elevation of a difierent form of the spring-pressed means for the packing ring; Fig. 3 is a like view of another form of the spring-pressed means; and Fig. 4: is a cross section of the packing ring on the line t 4 of Fig. l.

The packing ring A, of felt or other similar material, is split or open at the top and provided with ends A, A and on one of the ends A of the ring A is arranged. a leather cap B into which projects the other end A of the ring A. On the ends A and A are secured or formed apertured lugs C, C, in which is slidingly mounted a guide rod D projecting beyond these lugs and carrying at its outer ends a pair of stops D, D for limiting the sliding movement of the rod D in the lugs C and C. On the guide rod D is coiled a spring E, fastened at its ends to the lugs C and C. and this spring is attached at its middle to the middle of the guide rod I). The spring E is for this purpose reduced in diameter at its middle E to engage a reduced or flattened portion D of the rod D at Specification of Letters Patent.

the middle thereof intermediate the lugs C and C.

In the form shown in Fig. 2, the guide rod D is mounted on the lugs C C and is provided at its ends with stops D D and at the middle with a pin F, on which is fastened the middle portion of the spring E ccoilel on the rod D and secured to the lugs In the form shown in Fig. 3, the guide rod D is mounted to slide in lugs C and is provided with angular arms D D forming stops to limit the sliding movement of the rod D on the lugs C C Two springs E E are provided and coiled upon the guide rod D intermediate the lugs C C the spring E having its outer end attached to the lug C and its inner end secured to the rod D near the middle thereof, and the other spring E having its outer end secured to the lug C and its inner end to the rod D near the middle thereof. When the pachng ring is to be brought upon the axle, the ring is sprung open and the lugs thus forced apart. The lugs are then released, and the spring draws the ends of the rings against each other, so that the ring is pressed against the axle.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be per formed, I declare that what I claim is:

1. A packing for journal boxes and the like, comprising a split ring provided at its ends with apertured lugs, a guide rod extending through the lugs, and spring-pressed means engaging said lugs and secured to the middle of the guide rod.

2. A packing ring for journal boxes and the like, comprising a split ring provided at its ends with apertured lugs, a guide rod slidably engaging said lugs, and a spring coiled upon the said guide rod intermediate the said lugs, the spring being attached to the lugs and to the middle of the guide rod.

3. A packing for journal boxes and the like, comprising a split ring provided at its ends with apertured lugs, a guide rod slidably engaging the said lugs and projecting beyond the same, the ends of the guide rod having stops to limit the relative movement of the lugs and guide rod, and a spring coiled on the said guide rod intermediate the said lugs, the spring being attached to the lugs and also to the middle of the guide rod.

4 111 a packing, a split ring provided at its ends with lugs having apertures therethrough, a guide rod extending through said lugs and movable relatively to the same, said guide rod being provided at its ends with limiting stops for said lugs, and a spring mechanism secured to said rod and engaging said lugs for the purpose of forcing the ends of said split ring toward each other.

5. The combination with two elements movable toward and away from one another, of a spring extending between, and secured at its ends to, parts of said movable elements,

and a member extending loosely through, and guided by, said parts of said movable elements, said spring being secured at a central point to the oenter of said member, between the said parts of said movable elements.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
